Emma Lazarus - 10Y1 - 10/PLR Temperature and Rate of Reaction Question How does temperature affect the rate of reaction between sodium thiosulphate and hydrochloric acid? sodium thiosulphate + hydrochloric acid › sodium chloride + water + sulphur dioxide + sulphur Na2S2O3(aq) + 2HCl(aq) › 2NaCl(aq) + H2O(l) + SO2(aq) + S(s) Prediction I predict that the higher the temperature, the more quickly reaction will occur. This is because with heat, the particles of sodium thiosulphate and hydrochloric acid have more energy. This causes them to move around more. It works like this for all substances, not just those two. Chemical reactions require collisions, and if particles are moving around more quickly they are obviously more likely to collide. It is just like in a crowded street. If the people are moving quickly it is more likely that they will bump into each other then if they are moving slowly. It is in this...
